Hemolysis related to occluder, prosthetic valve, and prosthetic ring used for mitral valve annuloplasty are not very unusual. However, hemolysis related to transcathetor closure of post-myocardial infarction ventricular septal defect (PMIVSD) is infrequent. A close follow-up for spontaneous resolution with or without blood transfusion has been reported in a few cases. Occasionally, surgical retrieval is unavoidable or lifelong blood transfusion is required if surgery cannot be done because of higher risk. In this illustration, we have showed a close follow-up of a case of hemolysis induced by atrial septal occluder used for VSD closure after myocardial infarction...

: Background and aims: After Peroral Endoscopic Myotomy (POEM), the mucosal incision is closed with endoscopically applied clips. After each clip placement, a subsequent clipping device has to be introduced through the working channel. With the Clipmaster3, three consecutive clips can be placed without reloading which could reduce closure time. We performed a prospective study evaluating efficacy, safety, and ease of use. Closure using Clipmaster3 was compared to closure with standard clips...

Cardioembolic strokes are generally more lethal and disabling than other source of strokes. Data from PROTECT AF (Watchman Left Atrial Appendage Closure Technology for Embolic Protection in Patients With Atrial Fibrillation) suggest that strokes after left atrial appendage occlusion (LAAO) with the Watchman device are less disabling than those in the warfarin group. No data assessing the severity of strokes after LAAO with the AMPLATZER Cardiac Plug (ACP) are available. The objective of the study was to evaluate the severity of cerebrovascular events after LAAO with the ACP in a population mostly characterized by an absolute or relative contraindication to oral anticoagulation...

Large bore vascular access is becoming increasingly common for a range of interventional cardiovascular procedures. In the vast majority, percutaneous closure is preplanned and successfully achieved. However, for patients with percutaneous closure failure, or those requiring prolonged hemodynamic support, alternatives to percutaneous closure are required. Currently there are no approved vascular closure devices for delayed removal of large bore sheaths and therefore, manual hemostasis or surgical closure remains the only options...

Sequestrectomy alone represents a procedure for the treatment of lumbar disc herniation. For selected cases, an anulus closure device (ACD) can be implanted which may result in lower reoperation rates. However, comparative magnetic resonance imaging (MRI) changes and their clinical relevance of both procedures are unclear and have not been reported so far. Clinical and MRI data of patients after limited discectomy with ACD implantation (group ACD; N=45) and patients after sequestrectomy alone (group S; N=40) with primary lumbar disc herniation were compared retrospectively...

In the current era where percutaneous coronary interventions are increasingly performed day by day can device closure of congenital heart defects be far behind. We describe one unusual case of ventricular septal defect (VSD) in a child with absent inferior vena cava which was tackled in a novel way using hemiazygous vein as the conduit (access) to the right side of heart.

Transcatheter aortic valve (TAV) implantation within a failed bioprosthetic valve is a growing trend for high-risk patients. The non-compliant stent of the previous prosthesis may prevent full expansion of the TAV, which has been shown to distort the leaflet configuration, and has been hypothesized to adversely affect durability. In this study, TAV leaflet fatigue damage under cyclic pressurization in the setting of stent underexpansion by 0 (fully expanded), 1, 2 and 3 mm was simulated using finite element analysis to test this hypothesis...

OBJECTIVE: Surgical femoral cutdown for decannulation after veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is considered standard practice. However, access-site complications with this technique are not rare. The objective of this study is to evaluate feasibility, safety, and efficacy of a complete percutaneous decannulation procedure after VA-ECMO compared with the conventional surgical cutdown approach. METHODS: In 35 patients who were successfully weaned from VA-ECMO support, femoral artery and vein access sites were closed using a completely percutaneous approach in 15 patients, whereas 20 patients had conventional surgical cutdown for access-site closure...

PURPOSE OF REVIEW: Anticoagulant therapy effectively reduces the incidence of stroke in patients with atrial fibrillation (AF) but is underutilized and frequently contraindicated. The left atrial appendage (LAA) is the primary site of thrombus formation in AF patients. Surgical and percutaneous appendage closure has been evaluated as a site-specific therapy to reduce systemic thromboembolism. RECENT FINDINGS: We will review LAA closure techniques, examine recent outcome data, and discuss the indications for, and potential complications of, each approach...

Mitral stenosis (MS) is frequently associated with the development of atrial fibrillation (AF) as a consequence of hemodynamic and inflammatory changes in the left atrium. Both conditions predispose to thrombus formation, with frequent involvement of the left atrial appendage (LAA), and consequent increase in the incidence of systemic thromboembolic events. Percutaneous mitral valvuloplasty (PMV) reduces the risk of thromboembolism in patients with significant mitral stenosis. Percutaneous LAA closure is also associated with a reduction in thromboembolic risk in patients with AF, but there are no data regarding the use of this technique in patients with significant mitral valve disease...
